REMOVAL OF AZURE A DYE FROM AQUEOUS SOLUTIONS BY USING STRONTIUM CHROMATE – ZINC OXIDE NANOCOMPOSITE
Water is one of the most important natural resource for human. Water pollution is one of the major problems faced by the humans. Several methods for waste water treatment have been suggested in the last few decades. These methods are based on chemical, physical and biological processes. In this paper, the Photocatalytic degradation of cationic dye Azure A observed in aqueous solutions containing strontium chromate – zinc oxide nanocomposites as Photocatalytic material. The effect of various parameters such as pH of solution, concentration of dye, amount of photocatalyst and intensity of light on rate of degradation of Azure A dye has been studied. Synthesized nanomaterials were investigated by using XRD and EDX techniques. The reaction takes place more effectively at pH 8.5 and it plays very important role in the characteristic of textile wastewater and generation of hydroxyl radicals. A tentative mechanism for the photocatalytic degradation of Azure A dye has been proposed.
